(sqrt18 + 2 sqrt3)^2

sqrt18 = sqrt9 * sqrt2 = 3 sqrt2

(3 sqrt2 + 2 sqrt3)(3 sqrt2 + 2 sqrt3)

= 9 *2 + 6sqrt6 + 6 sqrt6 + 4*3

= 30 + 12 sqrt6 answer

(_/18+2_/3)^(2

=(3_/2^(2 + (2)(2_/3)(3_/2) + 2_/3^(2)

=18+ 12_/6 +12

=30+12_/6

hope this helps

Point A is located at -5/8 and point B is located at -2/8. What is the distance between points A and B

UNO [17]

I think those are coordinates of points, (-5,8) and (-2,8)
so you just need to use distance formula ((8-8)^2+(-2+5)^2)=0+9=9
square root 9=3

Find the area of the triangle, also am I correct???

Ierofanga [76]

Answer:

The area of the triangle is 10.92 cm².

Step-by-step explanation:

The formula for the area of a triangle is

$A=\frac{1}{2}bh$

where b is the length of the base and h is the height. We know that b = 2.8 and h = 7.8, so you would substitute into the formula:

$A=\frac{1}{2}(2.8)(7.8)=10.92$ cm²

Graph the function y = x3 + 6x2 + 2x – 11. Based on the graph, what is the largest possible x-value if y = 0?

professor190 [17]

Answer:

Step-by-step explanation:

The graph is done using Desmos. Just by substitution x = 1 will force the graph to go to y = 0, but graphs are not always that good. This one gets 1.111

to get y = 0. I'd use 1 if you had to answer it and a computer will mark it.
